It is the first deal between French aviation giant Airbus and Jetstar Pacific, which said in July it was planning to buy the 10 single-aisle A320 aircraft.

Vietnam Airlines, which owns a 70 per cent stake of Jetstar Pacific, will purchase 10 Airbus A350 planes, according to officials at a signing ceremony attended by Hollande and Vietnamese President Tran Dai Quang in Hanoi.

Vietnam's VietJet said it would buy 20 A321 planes to boost its current fleet of 34 planes, all of which are Airbus.

The VietJet deal comes after it purchased 100 passenger jets from US aircraft maker Boeing for $11.3 billion in May, during a visit by US President Barack Obama.
